Abstract

The invention provides an electric vehicle pre-charging device model selection method and equipment. A pre-charging device comprises a pre-charging resistor. The model selection method includes a pre-charging resistor model selection step which includes the steps: providing a model selection parameter input interface and a model selection result output interface; acquiring pre-charging input parameters by the model selection parameter input interface; calculating the target resistance value of the pre-charging resistor according to the pre-charging input parameters; outputting the target resistance value by the model selection result output interface to select the pre-charging resistor. The pre-charging input parameters include complete vehicle capacitance values, target pre-charging time,complete vehicle total voltage and pre-charging completion mark values, wherein the pre-charging completion mark values are specific values of target pre-charging voltage and the complete vehicle total voltage. By the aid of the simple input parameters, target parameters of the electric vehicle pre-charging device can be acquired, so that a user can rapidly and accurately select models of the electric vehicle pre-charging device, and pre-charging efficiency and user experience are improved.

Description

technical field [0001] The invention relates to the technical field of precharging, in particular to a method and equipment for selecting a precharging device for an electric vehicle. Background technique [0002] With the gradual popularization of electric vehicles, the demand for pre-charging of electric vehicles is also increasing. In the pre-charging process, it is particularly important to select a suitable electric vehicle pre-charging device. [0003] However, there is a lack of methods and equipment for selecting the pre-charging device for electric vehicles in the prior art, resulting in users being unable to quickly and accurately match pre-charging related parameters, thereby affecting user experience and reducing pre-charging efficiency. Contents of the invention [0004] A brief summary of one or more aspects is presented below to provide a basic understanding of these aspects. This summary is not an exhaustive overview of all contemplated aspects and is int...
